2017-04-08iio: xoadc: augment DT bindings a bitLinus Walleij
In order to accommodate in a logical manner for the premuxed channels in PM8921 and the similarly addressed channels in later PMICs, we need a twocell arrangement with premux and analog mux setting as a tuple to uniquely identify a hardware channel. These bindings are not yet in use, so it should be fine to augment them before we actually start using it in drivers and device trees. This scheme came out of lengthy discussions and reverse-engineering and reading of the few information sources we have.

2017-01-31iio: adc: add device tree bindings for Qualcomm PM8xxx ADCsLinus Walleij
This adds the device tree bindings for the Qualcomm PM8xxx ADCs. This is based on the existing DT bindings for the SPMI ADC so there are hopefully no controversial features.
